Princess cut diamonds are one of those topics that regularly come up in conversations with clients. My experience shows that people who choose the princess cut value modernity but don't want to forgo classic brilliance. Clients most often ask why one princess cut diamond looks spectacular, while another – despite similar parameters – loses its sparkle. In this guide, I will show you how to choose the perfect diamond, how much it really costs, and why you can buy it most safely and affordably at Diament Expert.

Princess Cut – modern form of classic beauty

Princess cut diamonds combine a square, geometric character with the intense brilliance typical of the brilliant cut – if you are looking for modernity, elegance, and a timeless effect, this choice truly makes sense, find out why!

The princess cut was developed in the 1970s and popularized in 1979 as a response to the need for a square diamond that would retain the light reflection known from the round cut. Earlier attempts included forms such as the emerald cut, cushion, marquise, or experimental profiles, but the princess proved to be an excellent compromise.

From my experience, people who choose the princess cut value modernity but don't want to give up classic sparkle. The princess is a diamond in a shape that looks great in both minimalist settings and vintage styles, and its variety is highlighted by the different types of princess cuts.

Technically, the princess cut is a diamond cut similar to a brilliant, but with a pyramidal structure. This form causes the stone to reflect light at different angles than a round or oval, which creates a very dynamic visual effect.

Princess diamond captivates with its sharpness and cutting perfection

A princess diamond dazzles with its sharp lines, distinct edges, and precision – when cut properly, it can appear optically larger than a round diamond of the same weight. See how to assess this!

A typical length-to-width ratio is 1.00–1.05 (square shape) and above 1.05 for rectangular versions. Clients most often choose stones close to 1.00, because then the diamond shape is most harmonious.

The princess cut has 57 to 76 facets – most commonly you'll find 57 or 58 facets, which distinguishes it from the classic brilliant (58). This number of facets in the princess cut affects the level of brilliance and how the stone reflects light.

An example from my appraisal:
– 1.06 ct princess cut diamond, G color, VS2 clarity
It looked optically larger than a 1.00 ct round diamond and cost 18% less.

Additional advantage: the facet structure means that clarity in the VS2–SI1 range is often perfectly sufficient.

Discover the princess diamond cut – choose jewelry that shines uniquely

The princess diamond cut is a precise cut that maximizes light reflection and creates a dazzling effect – if you want jewelry with character, it's an ideal cut to consider, especially if you are interested in different princess cut types.

Unlike step cuts (like the emerald cut), the princess offers dynamic sparkle and a higher level of brilliance, and clients appreciate the various types of princess cuts.

The biggest mistake investors make regarding the princess cut is relying solely on certificate tables. Two stones with identical parameters can differ dramatically in appearance. Therefore, we always check if the stone has been properly cut.

In practice:
– larger crown → better optical effect
– depth → better light reflection
– proper cut → real value of the stone

Choose uniqueness – princess diamonds for the discerning

Princess diamonds are a choice for those who want more than the standard – modernity, elegance, and an excellent choice for an engagement ring, and we offer various types of princess cuts.

It's a choice for people who appreciate style and quality. In a white gold ring, it looks especially good – the contrast enhances the stone's brilliance and shape.

Practical tip: the corner is a critical point, so the setting must protect the edge.
